Those aren't the jets you'll be flying on to Singapore from Australia -- but they are the ones that connect you onwards to numerous long-haul destinations, and on which you're likely to be spending the greater part of your total flight time.

"The retrofit programme is currently underway to bring the Business Class product in line with the A380 and 777-300ER and the upgrades should be completed in July of next year," an airline spokesperson confirmed to Australian Business Traveller.

"Amsterdam will be the first route on which the aircraft will be deployed, but we are not yet able to provide additional deployment details as these are still being finalised," SQ's spokesperson explained.

The refurb means that all SQ's long-distance flights have the new business class -- these upgraded planes plus flights on the Airbus A380 and Boeing 777-300ER.

Note that the refurb aircraft doesn't include the similarly-named Boeing 777-200 planes currently used on regional flights including Perth-Singapore, nor the Airbus A330 fleet seen on many Australian routes.

The cabin upgrades are all about knowing what to expect on your Singapore Airlines flight: "We're always looking at ways to improve our in-flight products to provide more comfort to our customers and critically, consistency across our regional routes," the SIA spokesperson told us.

I expect and hope that it means that the SQ flights to Christchurch and the non-777-300ER flights to Auckland will finally get the fully lie flat product. Both have been getting long past the tooth with Spacebeds for far too long (even though SQ has never discounted Business Class on those routes to fairly reflect the inferior product).
